Main difference between China PETROLEUM RESIN C5 & C9
C9 Resin factory introduce the products that are mainly used in paints, anticorrosive coatings, etc. C5 petroleum resins are also called C5 resins and aliphatic hydrocarbon resins. They are divided into three types: general-purpose, blended, and element-color-transparent. Light yellow or light brown flaky or granular solid, relative density 0.97-1.07. Softening point is 70 ~ 140 ℃. The refractive index is 1.512. Soluble in acetone, methyl ethyl ketone, ethyl acetate, trichloroethane, cyclohexane, toluene, solvent gasoline, etc. C5 and C9 fractions by-produced from petroleum resin petroleum cracking plant are a kind of thermoplastic resin produced through pretreatment, polymerization, distillation and other processes. It is not a high polymer, but an oligomer with a molecular weight between 300 and 3000.
C5 Hydrocarbon Petroleum Resin suppliers told us that the product has high adhesion, and China Hydrocarbon Petroleum Resin C9 has low adhesion.
C5 petroleum resin with low C5 and C9 odor can be mixed with other petroleum resins or used as additives. Because it has good compatibility with oil and other synthetic resins, it can be dissolved in a variety of solvents. It has the advantages of good water resistance, good acid resistance, low melting point, and good adhesion. There are more and more in many aspects. application..
60% of C5 petroleum resin used in adhesives is widely used as an adhesive. The industry has become a booming emerging industry involving structures and decoration in the construction industry, automobile assembly, tires, wood processing, packaging, binding, Sanitary products, footwear and other fields. Many petroleum resin adhesives, such as hot-melt adhesives, especially new ones, require pressure-sensitive tackifiers.
Hot melt adhesive is an adhesive applied to the object to be glued and cured after cooling. It is an industrial adhesive with a wide range of uses, mainly including: production of disposable sanitary products, such as women's sanitary napkins and baby diapers; carton sealing of food, beverages and beer; production of woodworking furniture; wireless binding of books; For labels and tapes, such as cables, cars, refrigerators, shoes, etc., hot melt adhesive must be firmly combined with the tackifier.
